Thanks. You were right, I had a stale version of 479. Compilation
succeeds and all tests pass on branch-3.2 with the latest patches 473,
479, 481, and 491.

It should be in 479. Perhaps you have a stale version of the patch.

Flavio,
I'm getting a compilation error for patch 491:

I see a reference to getWeight in both FastLeaderElection.java in
patch
491:
patches/ZOOKEEPER-491.patch:+
if(self.getQuorumVerifier().getWeight(n.sid) != 0)
src/java/main/org/apache/zookeeper/server/quorum/
FastLeaderElection.java
:
if(self.getQuorumVerifier().getWeight(n.sid) !=
0)
However, I don't see a reference to this method in patches 473, 479,
or
481. I also don't see a reference to this method in the trunk...

You're missing 491 from your set of patches.

This repro's in both branch-3.2, and branch-3.2+patches(473, 479,
481).
Basically, it seems like the nodes are electing pd4-zook02 to be
the
leader. However, pd4-zook02 seems to realize it's not supposed to
be
and
then disconnects everyone. Then they re-elect it again, and it
loops
over and over.

Note that we have 2 groups, composed of machines in 3 different
locations (dc1, pd1, and pd4). The idea is that only machines in
dc1
have voting rights, and the ability to become a leader. The
machines
in
the pods all have a weight of zero, and are not expected to
become
leaders, or to vote on transactions.
Let me know what I can do to help resolve this issue.
